Sequence number is represented among the figure: installing plate 1, outer gland 3, outer plate 5, clip plate 7, wearing piece 9, first through hole 10, flywheel 11, second through hole 12, bent axle 13, first attrition surface 14, axle spring 17, third through-hole 30, air cavity 32, second attrition surface 50, internal gear 52, axially protuberance 70, external gear 72, keyway 74 and protruding key 130.
The specific embodiment
Embodiment describes in further detail the utility model below in conjunction with accompanying drawing.
Referring to Fig. 1, Fig. 2 and Fig. 3; The wet clutch of this dieing machine comprises installing plate 1; The centre of installing plate 1 is provided with a longitudinal section and is the first circular through hole 10; The upper/lower terminal of this installing plate 1 is respectively arranged with the longitudinal section and is the second circular through hole 12, and installing plate 1 is installed on the punch press fuselage through second through hole 12.
The both sides of said installing plate 1 are respectively arranged with outer gland 3, outer plate 5, are provided with air cavity 32 between said outer gland 3 and the outer plate 5, and said outer gland 3 is provided with third through-hole 30, and this third through-hole 30 is connected with air cavity 32.
The side of said outer plate 5 also is provided with clip plate 7, and an end of said clip plate 7 is provided with axial protuberance 70.
Said clip plate 7 is sleeved on the bent axle 13, and the lateral wall of said bent axle 13 is provided with protruding key 130, and said clip plate 7 is provided with keyway 74 corresponding to protruding key 130 places.Like this when clip plate 7 when himself axis rotates, can be with bent axle 13 to rotate synchronously.
Said outer plate 5 is sleeved on and is contained on the axial protuberance 70, and outer plate 5 can be along the moving axially of bent axle 13, and said outer plate 5 is provided with internal gear 52, axially protuberance 70 is provided with external gear 72, and said internal gear 52 is engaged on the external gear 72.Because outer plate 5 and axial protuberance 70 are meshing with each other through gear, and axial protuberance 7 is rotated with outer plate 5 synchronously.
The right side of said outer plate 5 is provided with wearing piece 9; Wearing piece 9 is fixed on the flywheel 11; Described flywheel 11 is rotated under the drive of motor by belt, and the end face of said installing plate 1 is provided with first attrition surface 14, and said outer plate 5 is provided with second attrition surface 50 corresponding to first attrition surface, 14 places.Add man-hour, the roughness of said first attrition surface 14 is processed into 0.03mm.The roughness of second attrition surface 50 also is processed into 0.03mm.Certainly, if adopt high-precision machine tooling, its surface roughness can also suitably reduce.
Be provided with elastic parts between said clip plate 7 and the outer plate 5, preferred elastic parts is an axle spring 17, and described axle spring 17 is arranged between clip plate 7 and the outer plate 5 at interval.
When punch press needs work, make the following rotation of flywheel 11 in the drive of motor, in third through-hole 30, feed gas then to air cavity 32; Pressure in the air cavity 32 increases; Promote outer plate 5 and move right, from being close on the wearing piece 9, because flywheel 11 is rotating always; Thereby make outer plate 5 follow flywheel 11 to rotate together; Outer plate 5 rotates through driving clip plate 7 with clip plate 7 pitch wheels, and clip plate 7 drives bent axle 13 through protruding key 130 and keyway 74 and rotates, thereby makes punch press work.
When punch press need stop, stopping to feed gas, axle spring 17 promotes outer plate 5 and leaves flywheel, thereby makes flywheel idle running, and outer plate 5 is static, thereby makes bent axle 13 stop operating.And when axle spring 17 leaves outer plate 5, second attrition surface 50 on the outer plate 5 is close on first attrition surface 14 on the installing plate 1,5 moments of outer plate are stopped.So just effectively avoid outer plate 5 owing under action of inertia, be rotated further the drawback of certain angle, improved the precision of punch press greatly.
